Hi all

Can anybody guides me , Is there anyway to make double sided slider in Qt4.2.

That is there are 2 pointers in the sliders so that we can drag it frm both the sides i.e from right as welll as left.



Thanx

Take a look at http://libqxt.sourceforge.net. AFAIR it contains a double head slider.

Hi Wysota

Take a look at http://libqxt.sourceforge.net. AFAIR it contains a double head slider.

The above Link u sent to me of "QExtensionLibrary ", can be used in Qt4.1 .

And also tell me How to use this Extension Library in Qt4.1.

Thanx

[wysota]

But What is AFAIR...

"As far as I remember"

The above Link u sent to me of "QExtensionLibrary ", can be used in Qt4.1 .

So? You wanted to know how to implement a double headed slider. Take the sources and implement it for Qt3.
http://libqxt.sourceforge.net/docs/c...panSlider.html

And also tell me How to use this Extension Library in Qt4.1.

Link against it.

Hi. Unfortunately the version of QxtSpanSlider in libqxt svn trunk is pretty immature. Here are links to revised files:

• qxtspanslider.h
• qxtspanslider_p.h
• qxtspanslider.cpp

They will get merged back to the development branch after certain build system issues have been solved.

Hi

I m working on Qt4.1 on Intel MAC machine

Is it possible to install libqxt on MAC Operating System

Actually I tried to install libqxt

and when I make the file I got errors.

make[1]: *** [QxtApplication_x11.o] Error 1
make: *** [sub-src_gui-make_default] Error 2

pls tell me what should i do now.

[wysota]

Did you run configure first?

[merry]

Yes I run configure first.

Is it possible to install libqxt on MAC Operating System

I'm afraid it's not because nobody in the development team has a Mac.

pls tell me what should i do now.

I suggest you take the class, remove unnecessary includes and export macros and include it directly to your project. See the attachment.

Thanx

I ' ll try this...

QxtSpanSlider inherits QSlider so you can make it horizontal in the same way. Either pass Qt::Horizontal to the constructor or use QAbstractSlider::setOrientation().

Lower boundary value of the span:

• QxtSpanSlider::lowerValue() - returns the lower boundary of the span
• QxtSpanSlider::setLowerValue(int lower) - sets the lower boundary of the span
• QxtSpanSlider::lowerValueChanged(int lower) - a signal which is emitted whenever the lower boundary of the span changes

Upper boundary value of the span:

• QxtSpanSlider::upperValue() - returns the upper boundary of the span
• QxtSpanSlider::setUpperValue(int lower) - sets the upper boundary of the span
• QxtSpanSlider::lowerUpperChanged(int lower) - a signal which is emitted whenever the upper boundary of the span changes

In addition, QxtSpanSlider provides QxtSpanSlider::setSpan(int lower, int upper) and QxtSpanSlider::spanChanged(int lower, int upper).

How Can I add QSpinBox in the file "QxtSpanSlider" u had given me yesterday ,for showing lower head and upper head values in the spinboxes.

Do you mean how to connect corresponding signals and slots?

connect(lowerSpinBox, SIGNAL(valueChanged(int)), spanSlider, SLOT(setLowerValue(int)));
connect(upperSpinBox, SIGNAL(valueChanged(int)), spanSlider, SLOT(setUpperValue(int)));
connect(spanSlider, SIGNAL(lowerValueChanged(int)), lowerSpinBox, SLOT(setValue(int)));
connect(spanSlider, SIGNAL(upperValueChanged(int)), upperSpinBox, SLOT(setValue(int)));

connect(lowerSpinBox, SIGNAL(valueChanged(int)), spanSlider, SLOT(setLowerValue(int)));
connect(upperSpinBox, SIGNAL(valueChanged(int)), spanSlider, SLOT(setUpperValue(int)));
connect(spanSlider, SIGNAL(lowerValueChanged(int)), lowerSpinBox, SLOT(setValue(int)));
connect(spanSlider, SIGNAL(upperValueChanged(int)), upperSpinBox, SLOT(setValue(int)));
